best upgrade process for server

[Dale Scott]

Hi all, 

I'd like suggestions for a new basic server. I'm currently running my website and a number of web apps I use to demo enterprise work processes on a single-disk 11.3 server with a 2nd disk for periodic backups of the web apps and the occasional file system dump. I'm concerned about backups and recovery, and would like replace the server with a new ZFS-based system and a pool of three or four 1T SSDs. I'm not interested in laboring over spec's and tweaking the system out and I'm not storing the world's movie collection. I favor basic, mature parts and minimum time spent making decisions. 

Is the following migration strategy reasonable? Can I restore a dump from my single-disk system to a new bhyve/ZFS system? Can I copy the virtualbox-ose virtual disk file to the new system and bhyve will know what to do? I'm using the virtualbox-ose NAT to remap the vm IP address and port, will bhyve be able to do this? 

Thanks for your recommendations.
